Making moulds need to pay attention to the following issues:

First, do not only focus on product design, ignoring the mould manufacturing:

Some users in the development of products or new products trial production, often the initial focus only on product development and development, ignoring the communication with the mould making unit. After the initial determination of the product design programme, that is, in advance with the mould manufacturer contact has three advantages:

1, can ensure that the design of the product has a good forming process, will not be difficult to process the parts and modify the stereotypes design.

2, the mould maker can do design preparation in advance, to prevent hasty ill-considered, affecting the schedule.

3, the production of high-quality moulds, only the supply and demand sides work closely together, in order to ultimately reduce costs and shorten the cycle.

Second, do not just look at the price, but from the quality, cycle, service, all-round consideration:

1, there are many types of moulds, which can be roughly divided into ten categories. According to the part material, physical and chemical properties, mechanical strength, dimensional accuracy, surface finish, service life, economy and other different requirements, choose different types of mould forming.

2, high precision requirements of the mould needs to use high-precision CNC machine tool processing, and mould materials, forming process have strict requirements, but also need to use CAD / CAE / CAM mould technology to design, analysis.

3, some parts due to the special requirements of forming, moulds also need to use hot runner, gas-assisted molding, nitrogen cylinders and other advanced technology.

4, the manufacturer should have CNC, EDM, wire-cutting machine tools and CNC copy milling equipment, high-precision grinding machine, high-precision three-coordinate measuring instrument, computer design and related software.

5, general large stamping die (such as automotive cover mould) to consider whether the machine tool has a press edge mechanism, and even edge lubricants, multi-station progressive. In addition to stamping tonnage should also consider the punch, feeding devices, machine tools and die protection devices.

6, the above mould manufacturing means and technology is not every enterprise have and master. In the selection of collaborative manufacturers must understand its processing capacity, not only look at the hardware equipment, but also combined with the level of management, processing experience and technical force.

7, for the same set of moulds, different manufacturers offer sometimes a big difference. You should not pay more than the cost of the value of the mould at the same time, should not be less than the cost of the mould. Mould manufacturers like you to make a reasonable profit in business. Ordering a set of moulds quoted at a much lower price can be the start of trouble. Users must start from their own requirements, the full measure.

Third, avoid multiple collaboration, try to mould making and product processing a dragon:

1, with a qualified mould (test piece qualified), not necessarily produce a batch of qualified products. This is mainly related to the parts of the machine tool selection, forming process (forming temperature, forming time, etc.) and the operator's technical qualities.

2, with a good mould, but also a good forming process, ** is a one-stop collaboration, try to avoid multiple collaboration.
